El 58
A long list of seasonal Mediterranean small plates, ranging from coal-grilled octopus to vegetarian risotto to traditional Catalan sausage stew, is chalked up on the boards here each day. Inside it's casually hip, with exposed brick walls and vintage furniture; there’s a small back patio for al fresco dining as well as tables out front on the Rambla del Poblenou for excellent people-watching.
